After submitting the certificate signing request to the CA, the CA will sign the
request and return a signed copy of the certificate. Typically this will be sent
in PEM format, the same format used for the CSR and private key.

The certificate data can be imported in one of two ways:

Use pkicertificate<name>enter then copy and paste the PEM data

Copy the PEM format certificate file to the TNSR host, then use pkicertificate<name>import<file> to import from a file from the current
working directory.

The certificate data is stored in a file at
/etc/pki/tls/tnsr/certs/<name>.crt after entering or importing the contents.

First, make sure that the copy of the certificate file is in PEM format. The CA
may have delivered the certificate in PEM format, or another format. Convert the
certificate to PEM format if it did not come that way.

Next, copy the certificate file to TNSR and start the CLI from the directory
containing the certificate file. The filename extension is not significant, and
may be pem, crt, txt, or anything else depending on how the file was
delivered from the CA.
